• Oscillator is provided on the monolithic control with adopting On-Chip-

Trimming technology.

• Small temperature characteristics variation by adopting a comparator to

compensate for temperature on the control part.

• Low start-up circuit current (100uA max)

• Built-in Active Low-Pass Filter for stabilizing the operation in case of light

load

• Avalanche energy guaranteed MOSFET with high VDSS

• Built-in constant voltage drive circuit

• Built-in soft drive circuit

• Built-in low frequency PRC mode (≒20kHz)

• Various kinds of protection functions

Descriptions

IRIS-G6653 is a hybrid IC consists from power MOSFET and a controller IC, designed for Quasi-Resonant (including

low frequency PRC) fly-back converter type SMPS (Switching Mode Power Supply) applications. This IC realizes high

efficiency, low noise, downsizing and standardizing of a power supply system reducing external components count and

simplifying the circuit designs.

(Note). PRC is abbreviation of “Pulse Ratio Control” (On-width control with fixed OFF-time).

Features

Typical Connection Diagram

• The built-in power MOSFET simplifies the surge absorption circuit

since the MOSFET guarantees the avalanche energy.

• No VDSS de-rating is required.

• Pulse-by-pulse Overcurrent Protection (OCP)

• Overvoltage Protection with latch mode (OVP)

• Thermal Shutdown with latch mode (TSD)

Note1: The Pout (W) represents the thermal rating at Quasi-Resonant

Operation, and the peak power output is obtained by approximately

120 to 140% of the above listed. When the output voltage is low and

ON-duty is narrow, the Pout (W) shall become lower than that of

above.
